Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2007 GT Power Series 24 and 2005 GT Power Series 24.
- Gearing
2005 GT Power Series 24 has a 11% lower climbing ratio than 2007 GT Power Series 24.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
- Identity & price
2005 GT Power Series 24 had an original MSRP $150 lower than 2007 GT Power Series 24.
Original MSRP is the published list price when new, not today’s used-bike value.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.
Ratio2.56:1
Estimated speed at 90 RPMGear
Uses front tire 24×1.95; rear size isn’t listed.
Ratio2.28:1
Estimated speed at 90 RPMGear
Uses front tire 24×1.75; rear size isn’t listed.
How it works
Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.
Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
